ArrayCGH of Trichoderma reesei strains QM9123, QM9414, NG14 and RutC-30

Project description:Trichoderma reesei is the main industrial producer of cellulases and hemicellulases used to depolymerize biomass in many biotechnical applications. Many production strains in use have been generated by classical mutagenesis. In this study we characterized genomic alterations in hyperproducing mutants of T. reesei by high-resolution comparative genomic hybridisation tiling array. We carried out aCGH analysis of four hyperproducing strains (QM9123, QM9414, NG14 and RutC-30) using QM6a genome as a reference. ArrayCGH analysis identified dozens of mutations in each strain analyzed. 2.1 million oligonucleotide probe custom aCGH (HD2 format, RocheNimblegen) was designed according to T. reesei strain QM6a genome v2.0 (http://genome.jgi-psf.org/Trire2/Trire2.home.html). 14 samples are included in this set; 3 replicates of each strain (except two replicates of QM9123) were analyzed (four mutant strains and QM6a control strain for self-hybridization)

Systemic analysis of lactose metabolism in Trichoderma reesei identifies a lactose permease that is essential for cellulase induction

Project description:Lactose (1,4-0-M-CM-^_-d-galactopyranosyl-d-glucose), a by-product from cheese manufacture or whey processing industries, is known to induce the formation of plant biomass hydrolyzing enzymes needed for the biorefinery industry in the fungus Trichoderma reesei, but the reason for this induction and the underlying mechanism are not fully understood. Here, we used systems analysis of the Trichoderma reesei transcriptome during utilization of lactose. We found that the respective CAZome encoded glycosyl hydrolases specifically tailored for the attack of monocotyledon xyloglucan. In addition, genes for a high number of putative transporters of the major facilitator superfamily were also induced. Systematic knock out of them identified a gene whose knock-out completely impaired lactose utilization and cellulase induction in Trichoderma reesei. These data shed new light on the mechanism by which Trichoderma reesei metabolizes lactose and illuminate the key role of M-CM-^_-D-galactosides in habitat specificity of this fungus. We used two biological replicas of Trichoderma reesei growing on lactose, glucose and glycerol

Comparative analysis of the Trichoderma reesei transcriptome during ethanol fermentation under anaerobic and aerobic condition

Project description:In this study, the recombinant Trichoderma reesei strain HJ48 was employed to investigate the differences between anaerobic and aerobic fermentation of glucose, through genome-wide transcription analysis.Analysis of the genes induced under fermentation condition has revealed novel features in T. reesei. Our results how that many genes related to ribosome were expressed more highly under aerobic condition in HJ48.

Transcriptional landscape of XYR1 in Trichoderma reesei during the degradation of cellulosic material

Project description:Hypocrea jecorina (anamorph Trichoderma reesei) is one of the most well studied fungi used in biotechnology industry. This fungus is today a paradigm for the comercial scale production of different plant cell wall degrading enzymes, mainly cellulases and hemicellulases. The objective of this study was to analyze the transcriptional profiling of T. reesei (Δxyr1) grown in presence of cellulose, sophorose and glucose as the carbon source using RNA-seq approach.
